HashBeam: Enabling Feedback Through Downlink Beamforming in Unsourced Random Access
Jamison R. Ebert, Krishna R. Narayanan, Jean-Francois Chamberland
Unsourced random access (URA) has emerged as a candidate paradigm for massive machine-type communication (MTC) in next-generation wireless networks. While many excellent uplink sch…
Sparse Random Khatri-Rao Product Codes for Distributed Matrix Multiplication
Ruowan Ji, Anoosheh Heidarzadeh, Krishna R. Narayanan
We introduce two generalizations to the paradigm of using Random Khatri-Rao Product (RKRP) codes for distributed matrix multiplication. We first introduce a class of codes called S…
FASURA: A Scheme for Quasi-Static Massive MIMO Unsourced Random Access Channels
Michail Gkagkos, Krishna R. Narayanan, Jean-Francois Chamberland +1
This article considers the massive MIMO unsourced random access problem on a quasi-static Rayleigh fading channel. Given a fixed message length and a prescribed number of channel u…
Coded Demixing for Unsourced Random Access
Jamison R. Ebert, Vamsi K. Amalladinne, Stefano Rini +2
Unsourced random access (URA) is a recently proposed multiple access paradigm tailored to the uplink channel of machine-type communication networks. By exploiting a strong connecti…
Noisy Group Testing with Side Information
Esmaeil Karimi, Anoosheh Heidarzadeh, Krishna R. Narayanan +1
Group testing has recently attracted significant attention from the research community due to its applications in diagnostic virology. An instance of the group testing problem incl…
